[0002] High-voltage DC generators are one of the most commonly used and important devices in the power industry. They can output high voltage to meet various power demands. At the same time, their output voltage has the characteristics of high stability and low current.

[0014] In one alternative implementation, the flexible traction belt is a tank tire.

[0015] In one optional embodiment, the bottom box is fixedly installed on the lower side of the support frame. The bottom box is a hollow box structure used to store the disassembled voltage multiplier cylinder and cables.

[0019] Compared with the prior art, the beneficial effects of this application are:

[0020] 1. This application provides a DC high-voltage generator with a support frame consisting of a base and a vertical frame above it, forming a stable vertical support structure. A mounting plate is provided in the lower section of the vertical frame, and a lifting assembly is arranged between the mounting plate and the top rod at the upper end of the vertical frame, thus providing the structural basis for lifting the load-bearing platform, facilitating the lifting and adjustment of the load-bearing platform within a limited space. The load-bearing platform is connected to the lifting assembly, and its height is adjusted according to actual operational needs under the action of the lifting assembly, thereby achieving the lifting and adjustment of the voltage multiplier cylinder installed on the load-bearing platform. The voltage multiplier cylinder is installed on the load-bearing platform; when the height of the test object changes, adjusting the height of the load-bearing platform can adapt to the new working position.

[0021] 2. In this application, the lifting assembly employs a combination of a lead screw structure and a flexible traction structure, which respectively undertake the functions of main power transmission and synchronous auxiliary functions. The lead screw structure plays a leading role in the lifting of the platform, possessing excellent vertical rigidity guiding performance. The flexible traction structure forms a synchronous auxiliary path, not only providing traction for the platform's movement but also offering buffering and correction effects to a certain extent. Therefore, the lifting assembly using this combined lead screw and flexible traction structure arrangement enhances controllability and improves motion stability during the lifting process. A rocker arm is installed on the outer side of the vertical frame; the operator can manually rotate it to move the lead screw structure, causing the platform to move accordingly. The control method is intuitive, and the operation is relatively smooth.

[0022] 3. This application places the base box on the base and on one side of the vertical frame, structurally forming an integrated configuration with the entire support frame. The voltage multiplier cylinder is detachable after use, and its connected cable can be stored in the base box. Since the base box is part of the overall structure, there is no need for an external toolbox or additional temporary storage device; users can directly store the relevant components after use. This arrangement is more convenient in field operation and helps reduce the risk of collision or loss due to exposed components during transport. Simultaneously, the overall structure is more compact during relocation or retrieval, improving the portability and operational safety of the device. Furthermore, the voltage multiplier cylinder is electrically connected to the DC high-voltage generator control mechanism located outside the support frame via a cable. The DC high-voltage generator control mechanism, as a control unit, is separated from the voltage multiplier cylinder, thereby reducing operational risks. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0029] This application provides a DC high-voltage generator, which allows for easy adjustment of the voltage multiplier cylinder height to suit different equipment heights. It also provides a comfortable operating environment for users of varying heights. Specifically, the DC high-voltage generator provided in this application, as shown in Figures 1-3, includes: a base box 100, a support frame 200, a lifting assembly 300, a load-bearing platform 400, a guide assembly 500, a rocker arm 600, and a voltage multiplier cylinder 700.

[0030] The support frame 200 includes a base 210 and a vertical frame 220 fixedly installed in the middle of the base 210. A horizontally arranged mounting plate 221 is provided in the lower section of the vertical frame 220. A lifting assembly 300 is installed between the mounting plate 221 and the top rod 222 of the vertical frame 220. The lifting assembly 300 is connected to a bearing platform 400. The lifting assembly 300 adopts a lifting form that combines screw drive and flexible traction structure and can adjust the lifting height of the bearing platform 400. A rocker arm 600 for controlling the lifting action of the lifting assembly 300 is installed on the outer side of the vertical frame 220. A pressure multiplier cylinder 700 is detachably connected to the bearing platform 400. The pressure multiplier cylinder 700 is connected to a DC high voltage generator control mechanism 800 located outside the support frame 200 via a cable 710. A base box 100 located on one side of the vertical frame 220 is provided on the base 210.

[0031] In this embodiment, the support frame 200 consists of a base 210 and a vertical frame 220 above it, forming a stable vertical support structure. A mounting plate 221 is provided in the lower section of the vertical frame 220. The lifting assembly 300 is arranged between the mounting plate 221 and the top rod 222 at the upper end of the vertical frame 220, thus providing the structural basis for the lifting of the bearing platform 400, facilitating the lifting and adjustment of the bearing platform 400 within a limited space. The bearing platform 400 is connected to the lifting assembly 300, and its lifting height is adjusted according to actual operational needs under the action of the lifting assembly 300, thereby achieving the lifting and adjustment of the pressure multiplier cylinder 700 installed on the bearing platform 400. The pressure multiplier cylinder 700 is installed on the bearing platform 400. When the height of the test object changes, adjusting the height of the bearing platform 400 can adapt to the new working position. Compared with traditional fixed installation methods, this embodiment has advantages in terms of adjustment convenience, and the structure has strong adaptability, applicable to various work scenarios with different height requirements, reducing the obstacles to use caused by platform height limitations to a certain extent.

[0032] In this embodiment, the lifting assembly 300 employs a combination of a lead screw structure and a flexible traction structure, which respectively undertake the functions of main power transmission and synchronous assistance. The lead screw structure plays a dominant role in the lifting of the support platform 400, exhibiting excellent vertical rigidity guidance performance. The flexible traction structure forms a synchronous assistance path, not only providing traction for the movement of the support platform 400 but also offering buffering and correction effects to a certain extent. Therefore, the lifting assembly 300, with its combination of lead screw and flexible traction structures, enhances controllability and improves motion stability during the lifting process. A rocker arm 600 is installed on the outer side of the vertical frame 220. The operator can manually rotate the rocker arm to move the lead screw structure, enabling the support platform 400 to achieve corresponding displacements. The control method is intuitive, and the operation process is relatively smooth.

[0033] Furthermore, the base box 100 is mounted on the base 210 and located on one side of the vertical frame 220, structurally forming an integrated configuration with the entire support frame 200. The voltage multiplier cylinder 700 is detachable after use, and along with its connected cable 710, can be stored in the base box 100. Since the base box 100 is part of the overall structure, no external toolbox or additional temporary storage device is needed; users can directly store the relevant components after use. This arrangement is more convenient in field operations and helps reduce the risk of collision or loss due to exposed components during transport. Simultaneously, the overall structure is more compact during relocation or retrieval, improving the portability and operational safety of the device. Additionally, the voltage multiplier cylinder 700 is electrically connected to the DC high-voltage generator control mechanism 800 located outside the support frame 200 via the cable 710. The DC high-voltage generator control mechanism 800, acting as a control unit, is separated from the voltage multiplier cylinder 700, thereby reducing operational risks.

[0034] In some embodiments, the lifting assembly 300 includes a lead screw drive mechanism 310 and a flexible traction mechanism 320;

[0035] The lead screw transmission mechanism 310 includes a lead screw seat 311, a lead screw 312, a lead screw moving support 313, a first bevel gear 314, and a second bevel gear 315. The lead screw seat 311 is fixedly mounted on the mounting plate 221 and is used to rotatably connect the lower end of the lead screw 312. The lead screw 312 is arranged vertically and its upper end is rotatably connected to the top rod 222. The lead screw moving support 313 is threaded onto the body of the lead screw 312 and is fixedly connected to the bearing platform 400. The first bevel gear 314 is fixedly mounted on the bottom end of the lead screw 312 that extends downward through the lead screw seat 311. The second bevel gear 315 is rotatably mounted on the support plate 211 on the base 210. The second bevel gear 315 and the first bevel gear 314 mesh with each other for transmission. One end of the rocker arm 600 is fixedly connected to the second bevel gear 315 and can drive the second bevel gear 315 to rotate.

[0036] The flexible traction mechanism 320 includes two symmetrically arranged flexible traction belts 321 and two fixed plates 322 respectively connected to the flexible traction belts 321. One end of each of the two flexible traction belts 321 is fixedly connected to one side of the bearing platform 400, and the connection positions of the two flexible traction belts 321 and the bearing platform 400 are located on both sides of the connection position between the screw moving support 313 and the bearing platform 400. The two fixed plates 322 are symmetrically arranged inside the middle section of the two vertical rods 223 of the vertical frame 220. The other ends of the two flexible traction belts 321 are fixedly connected to the two fixed plates 322 respectively. The two flexible traction belts 321 are used for synchronous traction when the screw moving support 313 on the screw 312 drives the bearing platform 400 to rise and fall.

[0037] In this embodiment, a lead screw transmission mechanism 310 is provided in the lifting assembly 300 to construct the main power path for platform lifting. The lead screw seat 311 is fixed on the mounting plate 221 as the lower fulcrum of the lead screw 312 and bears the axial load function of the lead screw 312 during rotation. The lead screw 312 is arranged vertically, with its upper end rotatably connected to the top rod 222 of the vertical frame 220. The lower end of the lead screw 312 is rotatably connected to the lead screw seat 311, and extends out of the lead screw seat 311, engaging with the second bevel gear 315 through the first bevel gear 314 for transmission. The second bevel gear 315 is mounted on the support plate 211 on the base 210 and is linked with the rocker arm 600 through a fixed connection. In operation, power is input from the rocker arm 600, which is then reversed 90 degrees via the first bevel gear 314 and the second bevel gear 315 before being transmitted to the lead screw 312. This enables the vertical lifting and lowering of the lead screw moving support 313 on the lead screw 312, thereby raising and lowering the support platform 400 connected to the lead screw moving support 313 and the pressure multiplier cylinder 700 on the support platform 400. This mechanical transmission method eliminates the need for a motor or complex chain system, simplifying the structure and facilitating later maintenance and manual operation. It is suitable for applications with limited space or without electricity.

[0038] In the above embodiment, a lead screw 312 is externally threaded with a lead screw moving support 313, which is firmly connected to the support platform 400. Driven by the rocker arm 600, the lead screw 312 rotates, causing the lead screw moving support 313 to move axially along the lead screw 312, thus raising or lowering the support platform 400 as a whole. Because the threaded connection structure has a predictable transmission ratio, each rotation corresponds to a fixed stroke, which provides high repeatability for adjusting the height of the support platform 400. Manual fine-tuning of the platform position can be performed without the need for an electronic positioning device, making the operation simple and straightforward. For some work sites that do not require automatic control, this mechanical rotation-based lifting method can ensure stable operation while reducing dependence on the technical environment.

[0039] Furthermore, in this embodiment, the flexible traction mechanism 320 uses two flexible traction belts 321 as its core components. One end of each of these two flexible traction belts 321 is connected to the support platform 400, and the other end is connected to two fixed plates 322 in the middle of the vertical frame 220. The connection points of the flexible traction belts 321 are located on both sides of the connection between the lead screw moving support 313 and the support platform 400, which helps to maintain a relatively balanced force state during the lifting and lowering of the support platform 400. When the platform is driven up and down, the flexible traction belts 321 on both sides form a mirror-symmetrical tension path, which can alleviate the tilting problem caused by unilateral overload of the platform to a certain extent. In addition, the traction belts play an auxiliary role in limiting and guiding the platform during operation, which can reduce the frequency of structural displacement during the repeated lifting and lowering of the platform, and also help to extend the service life of the connection between the lead screw and the platform.

[0040] In some embodiments, the DC high voltage generator of this application further includes a guide assembly 500. The guide assembly 500 includes linear guide rails 510 disposed on the outer sides of both sides of the vertical frame 220 and guide sliders 520 that slide in cooperation with the two linear guide rails 510 respectively. The two guide sliders 520 are fixedly connected to both sides of the support platform 400.

[0041] In this embodiment, linear guide rails 510 are respectively provided on the left and right sides of the vertical frame 220, and are rigidly fixed to the vertical frame 220. The guide slider 520 is in sliding engagement with the linear guide rails 510. The carrying platform 400 can be constrained and guided along the linear guide rails 510 during lifting and lowering. In this embodiment, by symmetrically arranging the linear guide rails 510, the carrying platform 400, in addition to relying on the lead screw transmission to provide the main force during vertical movement, also obtains supplementary constraint and support through the guide components 500. This combined structure can suppress the swaying tendency during platform operation, helping to reduce the amplitude of swaying and the possibility of deviation, making the overall operation of the carrying platform 400 more stable.

[0042] Furthermore, the guide assembly 500 not only improves the motion accuracy of the support platform 400 but also enhances the ease of adjustment during actual use. When the platform is initially installed or the pressure multiplier cylinder 700 is replaced, the movement of the slider 520 on the linear guide rail 510 provides guidance and assistance for adjusting the height of the support platform 400, making the adjustment process smoother. In addition, as an independent structure, the guide assembly 500 does not interfere with the screw drive structure; its presence does not affect lifting efficiency but rather enhances the operational stability of the lifting structure through its guiding and limiting functions.

[0043] In some embodiments, the flexible traction belt 321 is a tank belt.

[0044] In this embodiment, the flexible traction mechanism 320 uses a tank tire as the flexible traction belt 321, which is composed of multiple articulated rigid segments. It possesses both flexibility and the ability to maintain a predetermined structural shape during movement. Compared to traditional webbing or soft traction structures, the tank tire exhibits a more stable trajectory during extension and retraction, and is less prone to twisting or deformation due to gravity or off-center loading. Its segmental connection structure limits the minimum bending radius of the traction path, ensuring a relatively constant distance between the traction belt and the platform edge or frame structure during the lifting and lowering of the carrying platform 400. This contributes to the controllability of the traction trajectory and reduces swaying caused by traction skew during the operation of the carrying platform 400.

[0045] Furthermore, the tank belt structure itself has guiding and limiting functions. In this embodiment, two flexible traction belts 321 are respectively connected to the support platform 400, and the other end is fixed to the fixing plate 322 of the vertical frame 220. When the platform is raised or lowered, the flexible traction belts 321 can automatically unfold and retract along a predetermined path without significant swaying, thus preventing the flexible traction belts 321 from shifting or flipping outward. This arrangement is particularly suitable for working environments with limited installation space.

[0046] In some embodiments, the base box 100 is fixedly disposed on the lower side of the support frame 200. The base box 100 is a hollow box structure used to store the disassembled pressure multiplier cylinder 700 and cables.

[0047] In this embodiment, the base box 100 is installed on the lower side of the support frame 200, forming a tight connection with the overall support frame 200 structure, and becoming part of the bottom structure of the device. The base box 100 adopts a hollow box form with a certain internal volume, which can be used to store components such as the pressure multiplier cylinder 700 and cable 710 disassembled from the support platform 400. In this way, it can be carried along with the whole device when the equipment is used, moved, or relocated, without the need for a separate toolbox or external storage structure, making the on-site storage process more direct and efficient.

[0048] Because the pressure multiplier cylinder 700 is relatively large and has a relatively precise surface structure, it is easily damaged by vibration or impact if directly exposed to the external environment when not in use. The base box 100, as a fixed structure connected to the support frame 200, has relatively strong rigidity and shock resistance, providing a closed and stable storage space for the pressure multiplier cylinder 700 and cable 710. In its stored state, the base box 100 also forms an isolation barrier against external substances such as dust and moisture, helping to reduce the risk of components becoming damp or contaminated. This makes the storage of components more organized and facilitates short-term or daily management in various working environments. Furthermore, the base box 100 is located in the lower part of the support frame 200, below the center of gravity of the equipment, and its fixed connection to the support frame 200 contributes to the overall stability of the device, making the body more resistant to tilting and overturning during lifting operations. This structure not only meets the storage requirements but also improves the stability of the equipment during use at the structural level.

[0049] In some embodiments, the bottom box 100 includes a box body 110 and a flip-up cover 120. The cover 120 is hinged to one side of the box body 110 by a hinge, and the cover 120 is closed on the box body 110 by a locking structure.

[0050] When it is necessary to store the voltage multiplier cylinder 700 or cable 710 inside the base box 100, simply lift the cover plate 120 for installation or removal; the entire process requires no disassembly of other parts. This structure facilitates frequent switching operations in a short period of time, making it particularly suitable for applications with high debugging frequency, ensuring both basic sealing and convenience. A locking structure is provided between the cover plate 120 and the box body 110 to prevent accidental opening of the cover plate 120 when it is closed.

[0051] In some embodiments, the support platform 400 is a rectangular frame structure. The top of the support platform 400 is provided with mounting holes for fixing the pressure multiplier cylinder 700 and can be used with fasteners for detachable installation of the pressure multiplier cylinder 700. The lower two sides of the support platform 400 are provided with sliding connecting plates 410 for connecting with the guide assembly 500. The sliding connecting plates 410 are fixedly connected with the guide slider 520. The sliding connecting plates 410 are provided with locking bolts 411 for locking the height position of the sliding connecting plates 410. The linear guide rail 510 is provided with multiple connecting holes 511 for the locking bolts 411 to connect.

[0052] In this embodiment, the support platform 400 adopts a rectangular frame structure design. The top of the support platform 400 is provided with holes specifically for installing the pressure multiplier cylinder 700, which can be used with corresponding fasteners to realize the assembly and disassembly of the pressure multiplier cylinder 700. In actual use, the pressure multiplier cylinder 700 may need to be replaced, such as when switching models or performing maintenance. This detachable structure can reduce the installation burden and improve the flexibility of on-site operation.

[0053] Furthermore, sliding connecting plates 410 are provided on the lower left and right sides of the support platform 400 and connected to the guide slider 520. This arrangement allows the support platform 400 to not only achieve vertical movement through screw transmission during lifting, but also to limit its trajectory with the lateral guidance path provided by the guide assembly 500. As a connecting component, the sliding connecting plate 410 is easier to maintain structural clarity than directly connecting the support platform 400 to 520, and helps to form a more stable and smooth sliding relationship between the support platform 400 and the linear guide rail 510.

[0054] In addition, to achieve height adjustment and position locking of the support platform 400, the sliding connecting plate 410 is provided with locking bolts 411, and the linear guide rail 510 is provided with multiple connecting holes 511. When the platform is adjusted to the target height, the bolts can be screwed into the designated holes of the guide rail to achieve mechanical limiting and fixing of the sliding connecting plate and the linear guide rail 510.

[0055] In some embodiments, the bottom of the pressure multiplier cylinder 700 is provided with a mounting flange 720, which is fixed to the top center of the support platform 400 by bolts.

[0056] In this embodiment, a mounting flange 720 is added to the bottom of the pressure multiplier cylinder 700. The flange adopts a flat ring structure and is fixedly connected to the top center area of ​​the support platform 400 by multiple bolts. This surface contact structure connected by the mounting flange 720 helps to evenly distribute the concentrated load to the support platform 400 structure. The installation position is selected in the middle of the support platform 400, which also makes the pressure multiplier cylinder 700 closer to the center of gravity of the support platform 400 in terms of spatial arrangement. This helps to reduce tilting or eccentricity caused by load offset, thereby improving the force balance state of the entire device during operation.

[0057] Furthermore, the mounting flange 720 is bolted to the support platform 400, a structure that allows users to quickly assemble and adjust the equipment on-site compared to welding or snap-fit ​​connections. When replacing, maintaining, or transporting the pressure multiplier cylinder 700, the operator only needs to loosen the bolts on the mounting flange 720 to quickly disassemble the cylinder, without the need for special clamps or tools. This disassembly and assembly structure improves operational efficiency and lowers the technical barrier to maintenance. In situations requiring the rotation of multiple models of pressure multiplier cylinders 700 for testing, a standardized flange + bolt interface can be used to maintain consistency in the overall machine operation, reducing adjustment errors caused by component replacement.

[0058] The method of using the DC high-voltage power generator provided in this application embodiment is as follows:

[0059] Before use, the operator can fix the pressure multiplier 700 to the middle area of ​​the top of the support platform 400 via the mounting flange 720 at its bottom, according to the actual test requirements. Tightening is done with bolts, facilitating quick on-site completion. After installation, the cable 710 on the pressure multiplier 700 can be connected to the DC high-voltage generator control mechanism 800 outside the support frame 200. To adjust the working height of the pressure multiplier 700, simply rotate the rocker arm 600 located on one side of the vertical frame 220. The rocker arm drives the second bevel gear 315 to rotate via transmission, which in turn drives the first bevel gear 314 and the lead screw 312 meshing with it. This allows the lead screw moving support 313 to move vertically along the lead screw 312, thereby raising and lowering the entire support platform 400 to the desired position.

[0060] During the lifting and lowering process of the support platform 400, two flexible traction belts 321 are connected to the support platform 400, playing a role in synchronous traction and auxiliary guidance, making the operation of the support platform 400 more stable and reliable. At the same time, the guide slider 520 in the guide assembly 500 forms a sliding fit with the linear guide rail 510, further standardizing the vertical running path of the support platform 400 and helping to reduce the possibility of deviation or local shaking of the support platform 400. After the platform reaches the target height, the locking bolts 411 on the sliding connecting plate 410 can be tightened to form a mechanical limit with the connecting hole 511 on the guide rail 510, realizing the fixed height of the support platform 400 and providing a more stable support foundation for subsequent tests.

[0061] After testing, if the voltage multiplier cylinder 700 needs to be disassembled or transported, the supporting platform 400 can be lowered to the bottom position. Then, the bolts on the mounting flange 720 can be loosened, and the voltage multiplier cylinder 700 and cable 710 can be removed together and placed in the base box 100 for storage. The cover plate 120 can be closed by hinge and locked using a locking mechanism to form a relatively closed storage state. The entire device has a compact structure and reasonable layout of components, which can easily complete the entire process from installation, adjustment, high-voltage testing to disassembly and storage. It is well-suited for high-voltage testing or inspection environments in power systems and has good field adaptability.

[0062] It should be noted that in this embodiment, the lifting assembly 300 is manually driven using a lead screw 312 in conjunction with a rocker arm 600. The entire platform's lifting path is also aided by the linear guide rail 510 and guide slider 520 in the guide assembly 500, creating a clear trajectory constraint during vertical movement. This structural arrangement ensures good motion stability during platform operation, achieving smooth operation even under varying load conditions and reducing swaying or jamming caused by unbalanced loads. For general power testing applications, this purely mechanical structure is sufficient to meet the basic requirements of the lifting function, eliminating the need for an additional electronically controlled drive system.

[0063] In addition, the flexible traction belt 321 in this embodiment is preferably a tank belt. This structure is composed of multiple segments and has a certain bending constraint force and guiding capability. It can form a stable contraction path and is suitable for synchronous guidance of the platform. However, the flexible traction mechanism 320 is not limited to using a tank belt. Other forms of traction components such as chain belts, steel wire belts, or engineering plastic sliding belts can also be selected according to the actual application scenario.

[0064] It should also be noted that while the base box 100 adopts a common cuboid structure in the illustration, its dimensions, proportions, and opening method are not uniquely limited. In actual design, it can be flexibly adjusted according to the geometry of the pressure multiplier cylinder 700 and the volume of the cable 710. The connection between the mounting flange 720 and the support platform 400 is bolted in this embodiment. In practical applications, structures with quick-release capabilities, such as pins, quick-locks, and clips, can also be used. As long as a stable connection can be achieved and the disassembly and assembly requirements are met, it can be used as an applicable structural form. Such structural substitutions will not substantially affect the core technical features and functional implementation involved in this embodiment.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
